Closing summary

We are going to wrap up our live coverage of Irma for now. Thank you for reading. Here is an update on where we stand at 6.30am GMT (2.30am ET) on Tuesday morning:

Irma has been downgraded to a tropical depression, having moved through Georgia and into Alabama by early Tuesday morning. It is bringing sustained wind speeds of 35mph, down from 50mph earlier on Monday.

10 people are dead across the United States, with six confirmed fatalities in Florida, three in Georgia and one in South Carolina as a result of the storm.

The death toll in the Caribbean hit 37 after the first death on Haiti was confirmed. Unicef have said donations and assistance from the international community will be needed to deal with the unfolding crisis. The UK has pledged £32m in aid while the French president, Emmanuel Macron, left on Monday to visit St Martin.

The scale of damage to the Florida Keys will become clearer by Tuesday 7am, when residents will be allowed back in. Communications were cut off for much of Monday, which restricted the flow of information. A report from the Key West city commissioner said food, water and fuel were running low, and there were unconfirmed reports of fatalities in the area, expected to be hard-hit after Irma made landfall there on Sunday.

Florida governor, Rick Scott, said he saw “devastation” on the Florida Keys, during a flyover. “I just hope everybody survived,” he said. “It’s horrible, what we saw.”

Record flash floods swept into Jacksonville out of the St Johns River, while an estimated 13 million people were left without power across the state in Florida.

Unicef calls for international donations

This latest story, from my colleague Helen Davidson, underlines the scale of destruction in the Caribbean, as estimated by international NGOs.

While much of the focus has been on European countries with overseas territories in the region (the UK, France and the Netherlands), Unicef have stressed the problem needs a much wider response from the international community.

In the words of Khin-Sandi Lwin, who is leading Unicef’s response in the Caribbean:

There is a general sense that [the British Virgin Islands] is British government territory and therefore the British will handle it.

We haven’t been able to raise the funds from other governments at the moment ... we need a much bigger international response to the funding that’s needed.

To date, the UK has earmarked £32m in aid for their territories, the French president, Emmanuel Macron, is en route to visit the region. Meanwhile, Canada has also announced a $160,000 aid package.

In Alabama, 25,000 homes are without power, mostly in eastern areas closer to Irma, which is currently over Georgia. However, Alabama Power say this is an improvement on 42,000 outages reported three hours ago.

In Florida, commercial flights from Tallahassee International Airport will resume on Tuesday morning.

Residents of the Florida Keys will be allowed back into their homes and businesses from 7am Tuesday.

Key Largo, Tavernier and Islamorada in Monroe County will be re-opened for those with proof of residence. For many, it will be a first opportunity to survey the damage, as communications in the area are still down.
